The Current Reality

Building emails still feels harder than it should be

Even with templates in place, teams face the same bottlenecks again and again.

Developers become blockers

Every content tweak requires a developer to edit HTML files. Quick updates take days, not minutes.

One mistake breaks everything

A missing closing tag or misaligned table can destroy an entire campaign layout across all email clients.

Templates multiply and diverge

Teams maintain multiple versions of 'the template' across Google Docs, Slack threads, and local folders.

This is where modular templates change the game.

Structure

How Modular Email Templates Work: The Anatomy

Every modular email is built from three core components that stack vertically—just like a real email in your inbox.

How Assembly Works

Emails are assembled by selecting modules from your library and stacking them between the header and footer. Marketing teams can edit text, swap images, and update links—all without touching HTML code or breaking the layout.

How Developers Set Up Modular Templates

Modular templates work by defining editable regions within your HTML code using simple markup tags:

<td mm-editable data-mm-label="Hero Headline">

This approach keeps your email structure safe while giving marketers full control over content. Learn more about tags in our documentation or explore pricing plans.
